  Climate Uncertainty: The Coolest Year for the Rest of Our Lives? with Zeke Hausfather

  Sep 30, 20261h 32m

  The El Niño now building in the tropical Pacific is unlike anything in the historical record, and it's arriving on top of decades of warming. Together, they could push global temperatures to roughly 1.8°C (3.2ºF) above pre-industrial levels next year, offering a preview of what may become the new normal within a decade. As the rate of warming continues to accelerate and public attention swings between alarm and fatigue, how can we clearly understand where the planet is actually headed and what it will take to adapt? In this episode, Nate is joined by climate scientist Zeke Hausfather to break down the numbers and metrics within climate science, and translate what they will actually feel like for humanity. He explains how global temperature is measured, what the new generation of IPCC scenarios reveals about plausible futures, and why there's still uncertainty in just how much warmer we'll get by the year 2100. Zeke also unpacks how declining aerosol pollution has sped up warming and other climate variables that have actively emerging research behind them. While certain amounts of warming are locked in, he emphasizes that there is still a wide difference between every degree of warming, and the actions we take now will determine climate futures for centuries to come. How does the IPCC attempt to incorporate the most unpredictable factor for climate models – human behavior – and what do their current projections estimate? If we reached zero emissions tomorrow, would the planet cool back down, or are we locked into the warming we already have? And in a world growing weary of crisis headlines, how can we hold the reality of climate change without tipping into denial or despair? About Zeke Hausfather: Zeke is a lead author of the IPCC Seventh Assessment Report, and was a contributing author to the Sixth Assessment Report. He also authored the climate trends chapter of the Fifth U.S. National Climate Assessment, and has testified as an expert witness before the U.S. House Committee on Science, Space, and Technology. At Berkeley Earth, Zeke helps produce one of the world's primary global surface temperature records. He is also a Climate Science Contributor at Carbon Brief. At Stripe, Zeke leads climate research for Frontier, a $2 billion advance market commitment accelerating permanent carbon removal.

  A State of the World Address: The Climate Speech We'll Probably Never Hear | Frankly 160

  Sep 25, 202615 min

  On the heels of Climate Week, Nate poses a thought experiment: What would a world leader's speech sound like if the difficult truths underpinning global heating – which are politically unsayable due to donors, borders, electoral campaigns, and other incentives – were laid bare to the public? Posing as this hypothetical world leader, Nate traces modern prosperity back to the extraordinary inheritance of ancient sunlight we discovered in the form of fossil fuels. Their extraction and depletion have made today's civilization possible, while simultaneously bringing forth dire consequences for Earth. He also outlines the deeper behavioral and cultural ways in which billions of individual choices become a system with its own logic and behavior, producing outcomes that no one person intended … or can control. Nate frames this moment in our more-than-human predicament as a test of collective maturity. The challenge we face is recognizing en masse that the energy system that enabled unprecedented material abundance is the same one now threatening the ecological stability we depend on. It also means realizing that there is no single solution or clean reset – instead, shifting the trajectory of the Superorganism requires responses from each of us, accumulated over time, slowly but surely. How exactly did the interests of the system diverge from the interests of the individuals within it? What weight does "collective maturity" carry as a response to the more-than-human predicament? And is it possible for a civilization built around perpetual growth to respond to limits without first experiencing collapse?

  The Escalation Trap: Is America's Strategy in Iran Backfiring?

  Sep 23, 20261h 7m

  The United States, a global superpower for the last several decades, is now locked into a battle for control over the region with the bulk of the world's remaining fossil fuel reserves. Despite U.S. military strength, Iran is not backing down, equipped with a new era of military technology. What happens if the U.S. strategy backfires against its leadership's intention, and what are the larger implications for the balance of geopolitical power? In this episode, Nate welcomes military historian and political scientist Robert Pape for an in-the-moment breakdown of the Iran war's trajectory. Drawing on more than two decades of modeling U.S. strikes on Iran, Pape lays out his central concept: the "escalation trap," in which tactical military success – such as killing leaders, hitting key assets, or a blockade – actually results in a strategic backfire as the attacked side is motivated by the need to survive. He layers this dynamic with the "Second Precision Revolution," which describes the rise of cheap, mass-produced drones that enable countries like Iran and Ukraine to withstand attacks from far stronger militaries. The two also discuss the tenuous position of the other Gulf States bordering Iran, the effects of this war on the financial power of the U.S., and the risk of an Iranian nuclear test in the next few months. Pape brings this all together to point toward the United States' position at the edge of losing its status as a lone superpower, pushing the world back toward regional power centers. What does the United States risk by continuing its strategy of brute punishment? How is the rest of the world adapting to the rapidly changing geopolitical gameboard? And if the United States global standing is relegated – and modern warfare is redefined by decentralized drone technology – what will it mean for stability and globalization more broadly? (Conversation recorded on September 15th, 2026) About Robert Pape: Robert A. Pape is Professor of Political Science at the University of Chicago specializing in international security affairs. His publications include Dying to Win: The Strategic Logic of Suicide Terrorism and Bombing to Win: Air Power and Coercion in War. His newest book, Our Own Worst Enemies: America in the Age of Violent Populism, is now available. Before teaching at the University of Chicago in 1999, Pape taught international relations at Dartmouth College for five years and air power strategy for the USAF's School of Advanced Airpower Studies for three years. He received his PhD from the University of Chicago in 1988. He is the director of the Chicago Project on Security and Threats.

  The Real Work: Four Things We Can't Afford to Get Wrong | Frankly 159

  Sep 18, 202633 min

  This week, Nate zooms out from recent headlines about climbing diesel prices, a thinning U.S. Strategic Petroleum Reserve, and inflationary bond markets to ask the deeper question: what is the real work that's required of us as the systems that underpin modern life begin to buckle? He draws on decades of tracing the links between energy, ecology, and economy to argue that our response to the predicament is not necessarily to prevent the inevitable economic deflation, but to begin to shape how society moves through it. From this premise, Nate outlines four areas of intervention that he feels are underattended, given the scale of what's coming. He calls attention to how we can help communities bend and not break as supply chains strain under pressure, and the ways we might shepherd ecosystems and species through this bottleneck of humanity's own making. He describes the sobering work of steering nations away from nuclear catastrophe when the proliferation fears that once restrained global powers have faded. Finally, he shows that underlying it all is the slower, generational project of recovering a sense of the sacred in a culture that has learned to measure everything in dollars. Woven through these areas of "real" work is the opportunity to rediscover meaning itself – including the idea that a life well spent is one oriented toward sustaining and enriching life beyond ourselves. Why should we view what we're facing as a predicament to mitigate and not a problem to solve? What would it take for society to absorb systemic shocks without fracturing the social bonds that hold it together? And in a culture built on extraction and convenience, what would it mean to reestablish a sense of the sacred in our relationship with the living world?

  Radical Simplicity: The Opportunities of a World in Collapse with Sarah Wilson

  Sep 16, 20261h 39m

  For years, the climate movement ran on the promise that, if we all rally hard enough, we could have it all: continue with our current system and save the planet. Yet the events of the past few decades have shown that this isn't quite the case, and in fact, climate is just one crisis among many produced by our growth-at-all-costs system. This raises the question: What happens when a culture built on the certainty of progress has to confront its own uncertainty? In this episode, Nate is joined by philosopher and author Sarah Wilson for an exploration of the emotions that come from learning about, processing, and then embodying the full extent of the metacrisis. Sarah shares her own emotional arc through this journey, and makes the case that "hope" (at least the version most of us think of) is no longer helpful, since it defers responsibility to some future savior rather than requiring anything of us now. In its place, she argues for truth to ground us, revealing the only path forward is to be "thoroughly human" – grieving, laughing, dancing, showing up for our neighbors. She and Nate also explore why prepping alone doesn't work, and that we should instead be working toward a radical simplification: an intentional shift toward a slower, more communal way of living. Why does the fear of uncertainty run so much deeper than we admit, and what happens to us once we stop resisting it? What emotions and opportunities do we make room for when we let go of false hopes that someone else will solve our crises? And if collapse is actually a slow unraveling of the system we've built our lives around, what would it look like to meet it with the same sense of duty and connection that has always seen humans through hard times? (Conversation recorded on September 10th, 2026) About Sarah Wilson: Sarah Wilson is a multiple-time New York Times and Amazon bestselling author, social philosopher, international keynote speaker, minimalist, and philanthropist. She edited Cosmopolitan magazine Australia at 29, founded the global I Quit Sugar movement, hosted the most-watched non-sports broadcast TV series in the nation's history – Masterchef Australia – and wrote the bestseller First, We Make the Beast Beautiful, which Mark Manson described as "the best book on living with anxiety that I've ever read." Her book, This One Wild and Precious Life, won the US Gold Nautilus Prize, and she has been ranked in the top 200 most influential authors in the world (two years in a row). Her latest book, I Eat the Stars, is now available globally. Sarah lives nomadically, leading dynamic, global conversations about modern philosophy, creativity, existential risk and climate change via her keynote speaking, Wild podcast, and her Substack and social communities (of 550,000 subscribers).
